Anti-shaking device for crane

Abstract

The invention relates to the field of cranes, in particular to an anti-shaking device for a crane. The anti-shaking device comprises a gantry and a moving mechanism. An anti-shaking device body is arranged under the moving mechanism. The moving mechanism comprises a first electric hoist and a second electric hoist which are arranged in a spaced mode. The two sides of the first electric hoist are each provided with a connecting plate. The first electric hoist and the second electric hoist are each provided with a stay. The stays are sleeved with clamping parts. The anti-shaking device body comprises a hook assembly and a guide assembly fixedly connected to the top of the hook assembly. According to the anti-shaking device, the four end spring design of a buffer pressure reducing part on a hook body is used, the stays can be downwards pressed and tightened manually through the clamping parts arranged on the stays, and thus shaking force of an object in the horizontal direction and vertical direction is reduced. The anti-shaking device is simple in structure, the operation safety coefficient during object suspension can be improved, and service life of equipment can be prolonged.

Description

technical field [0001] The invention relates to the field of cranes, in particular to an anti-sway device for a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as crane, aerial crane, crane. The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number. The existing bridge cranes hang objects through the hooks under the mobile device, and the mobile device ...

AI Technical Summary

Problems solved by technology

The existing bridge cranes hang objects through the hooks under the mobile device, and the mobile device moves on the top of the gantry crane of the bridge crane, so as to realize the movement of the hoisted objects; but at the same time, this structure still has certain defects. The problem is that, When the load is just hoisted, the load will shake in the horizontal direction, which reduces the safety factor in the operating environment, and when most of the hooks are unloaded, it is necessary to manually toggle the anti-slip buckle on the hook to make the load Get off the hook and add manual labor
